Anilox Roller's Type and Structure
The anilox roll is a very important part in the ink transfer part. What is the structure of anilox roll? What are its categories?
From the view of surface structure, it is mainly composed of roll core, substrate and surface coating. The base material commonly used is electroplating copper, which is the basis for making anilox roller unit. The surface coating is made of metal chromium or ceramic, which is mainly used to improve the wear resistance of anilox roll and prevent the corrosion of solvent.
Classification of anilox roll
According to the different surface coating of anilox roll, it can be divided into metal chrome anilox roll and ceramic anilox roll. From the comparison of engraving accuracy, printing resistance, ink transfer performance and ink release performance, ceramic anilox roller has more advantages.

2. The anilox roll can also be classified according to the ink shape on it. There are several common ink hole shape: hexagonal prism, quadrangular pyramid, quadrangular prism, trapezoidal section, and additional channel ink hole. The opening and depth of the ink hole have a considerable impact on the ink transfer performance of the anilox roll. The greater the opening and the shallower the depth, the better the ink transmission. Among the above ink shape, the hexagonal inking hole has a large opening, so the inking and inking performance is good, so this shape of ink is often used.
3.The number of lines of the anilox roll is one of the important parameters of the anilox roll. It refers to the number of ink holes per unit length on the surface of the anilox roll, which also has a very important impact on the ink transfer. In general, the higher the number of lines on the anilox roll, the smaller the amount of ink transferred. In addition, the anilox roll with different number of lines also has different application scope. When printing areas are large, you can consider using an anilox roller with a small number of lines. On the contrary, when printing fine images or small characters and lines, the anilox roller with higher number of lines should be used.
